Skin and Integumentary System Quiz

While examining a crime scene, Abigail notices unique patterns left behind on a glass surface. She recalls that these patterns are formed by a specific layer of the skin that has dermal papillae, is responsible for fingerprints, and is full of connective tissue. Which layer is it?

• Stratum corneum

• Papillary layer - dermis

• Subcutaneous layer

• Stratum basale

While studying how the skin heals after a cut, Oliver learns that there is a layer where constant cell division takes place to replace lost or damaged cells. Which layer is this?

• Stratum Basale

• Stratum corneum

• Dermis

• Arrector pili
